I have come to the conclusion that Darwinism is not a testable scientific theory, but a metaphysical research programme.
Interpretation
Popper critiques Darwinism as more of a philosophical framework than a strict scientific theory.
In this quote, Karl Popper argues that Darwinism should not be classified as a scientific theory because it lacks the capability to be tested or falsified. Instead, he views it as a metaphysical approach to understanding biological evolution, which suggests that its principles are more about a broader philosophical outlook on life and nature rather than empirical science that adheres to rigorous testing standards.
In practice
This quote can be used in a scientific discussion on the validity of evolutionary theories.
The growth of our knowledge is the result of a process closely resembling what Darwin called 'natural selection'; that is, the natural selection of hypotheses: our knowledge consists, at every moment, of those hypotheses which have shown their (comparative) fitness by surviving so far in their struggle for existence, a competitive struggle which eliminates those hypotheses which are unfit.
If you can't say it simply and clearly, keep quiet, and keep working on it till you can.
No particular theory may ever be regarded as absolutely certain.... No scientific theory is sacrosanct.
The belief in a political Utopia is especially dangerous. This is possibly connected with the fact that the search for a better world, like the investigation of our environment, is (if I am correct) one of the oldest and most important of all the instincts.
A rationalist is simply someone for whom it is more important to learn than to be proved right; someone who is willing to learn from others - not by simply taking over another's opinions, but by gladly allowing others to criticize his ideas and by gladly criticizing the ideas of others
Thus science must begin with myths, and with the criticism of myths; neither with the collection of observations, nor with the invention of experiments, but with the critical discussion of myths, and of magical techniques and practices.
I've had a chance to fly a lot of different airplanes, but it was nothing like the shuttle ride.
I hope that some day scientists can be considered heroes again, instead of Paris Hilton.
Until now the theory of infinite series in general has been very badly grounded. One applies all the operations to infinite series as if they were finite; but is that permissible? I think not. Where is it demonstrated that one obtains the differential of an infinite series by taking the differential of each term? Nothing is easier than to give instances where this is not so.
I take no pleasure in the fact that the scientific predictions Iβve relayed to popular audiences turn out to be true.
The imposing edifice of science provides a challenging view of what can be achieved by the accumulation of many small efforts in a steady objective and dedicated search for truth.
HOMOEOPATHY, n. A school of medicine midway between Allopathy and Christian Science. To the last both the others are distinctly inferior, for Christian Science will cure imaginary diseases, and they can not.
